Built for serious racers, the UPR 8.8 Rear Coil Over Shock Kit with Viking Crusader shocks delivers uncompromising performance and tuning capability for your Mustang. Designed specifically for 8.8 rear axle applications, this system is ideal for custom drag race builds that demand maximum adjustability, strength, and tire clearance.
This kit is centered around Viking Performance C309 Crusader double adjustable shocks, offering 22 rebound adjustments and 19 compression settings for a total of 418 valving combinations. The shocks are fully rebuildable and revalveable, allowing racers to fine-tune performance with interchangeable internal components.
